Now as beet or mangold is only introduced to new countries by means of seed, it follows that fungus spores must necessarily have been conveyed along with the seed. The disease h

In bad cases, the plant is greatly injured and the crop ruined. This fungus disease, caused by Uromyces phaseoli var. iypica, is common in the state but causes the most serious damage on winter string beans, particularly the Kentucky Wonder variety, grown in frostless districts of southern California. Dusting or spraying with sulfur (p. 74) at the first appearance of rust is of some value in control but has never proved entirely satisfac- tory. Se

In Puccinia Malvacearuni Moreau occasionally found a difference in size between the fusing cells, and Werth and Ludwig observed the migration of the nucleus of the smaller cell into the larger (fig. i84«).

The spores, for instance, of Sordaria fimiseda, de Not. have at their apex a germ-pore which is closed only by the outermost lamella of the membrane (Fig. 52). The germ-pores of the uredospores which I have examined,' those of Puccinia for example and Uromyces, are sharply defined round hole

The close agreement which has been found in this respect between the manner of formation of spore and of peridium of the aecidia and uredinia is suggestive. In Uromyces Glycerrhizae, plas- mogamy appears to occur somewhere on the mycelium, as the hyphae which form the uredinium are already binucleate (Olive, 1913). These primary uredinia which have arisen on the uninucleate mycelium often differ in their appearance from the secondary ones formed later on the binucleate mycelium, e.g., they are distinguished by a greater

In some genera, as in Puccinia, Uromyces, Phrag- midium and Triphragmium, they are surrounded by a margin of peri- physes or intermingled in the interior with paraphyses; and in Hemileia the stipes are joined together into a fascicle which emerges from the stoma bearing at its tip a small head of urediniospores. Both types of uredinia have one thing in common, that their spores arise (as the aeciospores) as daughter cells of an i
